How can PHP developers troubleshoot and resolve issues related to displaying special characters, like spaces, in input fields on a website?

Special characters, like spaces, in input fields on a website can be displayed incorrectly due to encoding issues. PHP developers can troubleshoot and resolve this by ensuring that the proper character encoding is set in both the HTML form and the PHP script that processes the input. Using functions like htmlspecialchars() can help encode special characters properly before displaying them on the website. 

// Set the character encoding for the HTML form
<meta charset="utf-8">

// Process input field in PHP script
$input = htmlspecialchars($_POST['input_field']);

// Display the sanitized input
echo $input;
